JOHN FLANAGAN, or NEWBURG, NEW YORK.

STOP-COCK.

SPECIFICATION forming part of Letters Patent No. 242,910, dated June 14, 1881. Application filed February 23,1881. (Modem T 0 all whom it may concern:

Be it known that 1, JOHN FLANAGAN, of Newburg, in the county of Orange and State of New York, have invented a new and useful Improvement in Stop-Cocks, of which the following is a full, clear, and exact description.

The drawingisa plan view, partly in section, ot ny improvement.

The-object of this invention is to facilitate the thawing out and removing obstructions from water-pipes.

Theinvention consistsin conslructinga stopcock with an inclined or slightly-curved branch pipe, so that a steam-tube can be readily inserted through or a force-pu mp connected with the stop-cock for thawing out or removing ob structions from pipes, as will be hereinafter fully described.

A represents the body of the stop-cock, the ends of which ale constructed in the ordinary manner, so that the said ends can be secured to the adjacent ends of a pipe.

B is the plug, which is constructed and operated in the ordinary manner.

In the body A is formed a branch, 0, projecting in the direction of the middle part of the stop-cock and inclined or slightly curved outward at each angle, as shown in the drawin g, so that a steam-tube can be readily inserted through the stopcock to thaw out the pipe when frozen.

This improvement is especiallyiutended for service-pipes, so that, should the said pipes freeze between the house and the water-main, the said pipes can be thawed out without its being necessary to dig up the street or cut the tion back into the main.

The branch 0 is closed with a screw cap or plug, D, so that it can be readily opened when required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- As an improved article of manufacture, a stop-cock having the end-tapered body A A,

the median plug B, and the internally endthrea-ded inclined pipe (3, provided with screw plug D, as shown and described.
